* compile, config.guess, config.sub, depcomp, install-sh, missing:
Remove; autoreconf can supply them.

* Makefile.in (sync-from-gnulib): Don't sync config.sub,
config.guess, install-sh.  Pass -i to autoreconf.

* autogen/update_autogen (genfiles): Add compile, config.guess,
config.sub, depcomp, install-sh, missing.  Pass -i to autoreconf.
Discard non-error output from autoreconf in -q case.

* autogen/compile, autogen/config.guess, autogen/config.sub:
* autogen/depcomp, autogen/install-sh, autogen/missing: New files.

* autogen/copy_autogen: Add compile, config.guess, config.sub, depcomp,
install-sh, missing.

* autogen/README: Add compile, config.guess, config.sub, depcomp,
install-sh, missing.

* INSTALL.BZR, admin/make-tarball.txt: Add -i to autoreconf args.

* .bzrignore: Add compile, config.guess, config.sub, depcomp,
install-sh, missing.

* ido.el (ido-read-internal): Simplify with read-from-minibuffer.
(ido-completions): Remove unused arguments.  (Bug#8329)

* lisp/minibuffer.el (completion--flush-all-sorted-completions):
Remove itself from hook.
(completion-at-point): Let the functions perform the completion
immediately and return nil or t.
* lisp/comint.el (comint-dynamic-complete-functions): Now identical to
completion-at-point-functions.
(comint-dynamic-list-input-ring): Remove unused var `index'.
(comint--match-partial-filename, comint--unquote&expand-filename):
New funs, split from comint-match-partial-filename.
(comint-dynamic-complete): Use completion-at-point.
(comint-dynamic-complete-filename): Use comint--match-partial-filename.

* lib-src/ntlib.c: Include <ctype.h>.

* nt/cmdproxy.c: Include <ctype.h>.
  (make_absolute): Remove unused variable `i'.

* src/w32fns.c (x_set_menu_bar_lines): Remove unused variable `olines'.
  (w32_wnd_proc): Pass NULL to Windows API, not uninitialized buffer.
  (Fx_close_connection): Remove unused variable `i'.

* src/w32font.c (w32font_draw): Return number of glyphs.
  (w32font_open_internal): Remove unused variable `i'.
  (w32font_driver): Add missing initializer.

* src/w32menu.c (utf8to16): Remove unused variable `utf16'.
  (fill_in_menu): Remove unused variable `items_added'.

* src/w32term.c (last_mouse_press_frame): Remove static global variable.
  (w32_clip_to_row): Remove unused variable `f'.
  (x_delete_terminal): Remove unused variable `i'.

* src/w32uniscribe.c (uniscribe_shape): Remove unused variable `nclusters'.
  (NOTHING): Remove unused static global variable.
  (uniscribe_check_otf): Remove unused variable `table'.
  (uniscribe_font_driver): Add missing initializers.

Without this fix, "This special-form is advised." won't be correctly
fontified.

Files that were merged into other files have been kept.

* Makefile.in (mkdir): Use `install-sh -d' instead of mkinstalldirs.
(sync-from-gnulib): Don't sync mkinstalldirs.

* make-dist: Don't distribute mkinstalldirs.

* leim/Makefile.in (install): Use `install-sh -d' rather than mkinstalldirs.

* lib-src/Makefile.in ($(DESTDIR)${archlibdir}):
Use `install-sh -d' rather than mkinstalldirs.

* configure.in, doc/emacs/Makefile.in: Update comments.

* admin/notes/copyright: Remove mkinstalldirs.

* lisp/eshell/esh-opt.el (eshell-eval-using-options):
Do not bind unused local variable `eshell-option-stub'.

* src/xterm.c (x_clear_frame): Remove XClearWindow call.  This appears
not to be necessary, and produces flickering.

the first time through the loop, since we know p0 < p1 then.
This also avoids a gcc -Wstrict-overflow warning.

and fall back on emacs-mule or utf-8-emacs.

mm-view.el (mm-display-inline-fontify): Make mode optional, and call normal-mode if not set. Set temp buffer unmodified to avoid kill-buffer query.
 (mm-inline-text): Render normal text with fontification whenever possible.
gnus-sum.el (gnus-summary-save-parts-1):
gnus-art.el (gnus-article-browse-html-save-cid-content)
 (gnus-article-browse-html-parts, gnus-mime-delete-part)
 (gnus-mime-copy-part, gnus-mime-inline-part, gnus-insert-mime-button):
 Use `mm-handle-filename'.
mm-util.el (mm-handle-filename): New function, return the filename of an handle.

* image.el (image-type-file-name-regexps): Make it variable.
  `imagemagick-register-types' modifies it, and the user may want
  to add new extensions for known image types.
  (imagemagick-register-types): Throw error if not using ImageMagick.

because point is not located after rcirc-prompt-end-marker.

leading to a memory leak, possible in functions like
load_charset_map_from_file that can allocate an unbounded number
of objects.

that could (at least in theory) be that large.

This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.

This is less likely to overflow, and avoids undefined behavior if
overflow does occur.  All callers changed.  Use strtoul to scan
for the unsigned long integer.
